MS09 Emergency Lighting:-

Whenever there is a loss of mains lighting in a fire condition it is likely that confusion and accidents will happen. Therefore the need for emergency lighting is important for two principal reasons, the first is to reveal a safe exit out of an emergency situation, the second being the avoidance of any hazards which may be present along the escape route. In this edition we consider the merits and virtues of emergency lighting.


MS08 Fire Suppression Systems:-

Since the discovery of the hole in the ozone layer over the South Pole, environmental moves and associated research led to the Vienna Agreement. This was rapidly followed by the signing of the Montreal Protocol, under the United Nations Environment Programme relating to substances, which deplete the ozone layer. Such international agreements have led to the rapid cessation of further production of halons due to their high ozone depletion characteristics. However considering the number of existing installations dependent upon halons in the UK, it was necessary to introduce transitional arrangements. Although users can purchase halon to recharge their systems via the Halon Bank managed by the Halon Users Consortium, this supply cannot be sustained so extensive research has been undertaken into the development of halon alternatives.


MS07 Fire Safety & the Disabled:-

Requirements for the provision of disabled access in buildings was first introduced into the Building Regulations over 15 years ago. Since then more detailed requirements have been incorporated in addition to other anti-discriminatory legislation, which place a statutory duty of care on building designers and occupiers to ensure that adequate measures are incorporated into new and existing buildings to enable the safe evacuation of people with disabilities.


MS06 Fire Risk Assessments:-

The risk of fire has various implications to any organisation not only in terms of life, but also in the risk to the building fabric / contents and the continuity of the organisation’s activity or indeed its continued existence. Risks may exist which are peculiar to the operation of the premises in terms of processes, occupation or perhaps the nature and extent of the building structure. Specific and general threats need to be identified and this qualification and quantification process forms the basis of a fire risk assessment.


MS05 Dealing with False Alarms:-

When a business is being constantly interrupted by false alarms, the fire alarm and detection system which causes them becomes a liability and eventually may be ignored with potentially disastrous results. Following on from the previous bulletin, "Choosing a Fire Alarm System", we now consider the subject of preventing unwanted false alarms.


MS04 Choosing a Fire Alarm System:-

Choosing the correct fire alarm system often requires a fine balance between what is required in order to provide early warning in the event of a fire, the need to satisfy legislation and the issue of cost against risk for life safety and property protection. In this edition we consider the options which need to be reviewed in order to ensure the suitability of a fire alarm system.


MS03 Fire Doors & Screens:-

When fire upgrading works are required to premises which contain specialist joinery items, care must be taken when meeting the requirement of the fire certificate to avoid unnecessary replacement and potential conflict with planning and heritage bodies. In this edition we consider the method of upgrading timber-panelled doors from 15 minutes fire resistance to over 30 minutes without any outward change to the appearance of the door.


MS02 Sprinklers:-

It has long been accepted by those involved in fire safety that the most effective means by which to control an outbreak of fire is the installation of automatic fire suppression. Automatic fire suppression systems are designed to detect a fire at an early stage and depending upon the nature and development of the fire, either to control or extinguishes the outbreak. In this edition we concentrate on the category of fire protection and in particular the aspect of fire suppression by fixed and automatic systems.
